Abstract
10,425. Lecoche, J. May 13. Brakes.-A worm and wheel in gear, and of a pitch greater than the angle of friction, are arranged to serve as a locking-device, which may be made effective in either or both directions about the axis of the wheel, and may be applied, as shown in Fig. 2, to hold a brake &c. lever. The worm d is mounted on a spindle with pointed ends h carried in lugs f on the pivoted lever k and is in engagement with a fixed sector p. When the pointed ends h are supported by cover-plates i, the worm spindle rotates freely, and the lever can be adjusted, but, when the cover-plates are removed by means of an arm s, the worm ends abut against the lugs f, and the frictional resistance prevents rotation of the worm, thereby locking the lever k to the sector.
